6th grade math

2. 9.1 – Understanding Percent

3. Using a Grid to Model Percents
A percent is a ratio that compares a number to 100
The symbol % is used to show a percent

4. You Try!
Ex: The free-throw ratios for three basketball players are shown: Player 1: Player 2: Player 3:
Rewrite each number as a ratio compared to 100. Then shade the grid to represent the free-throw ratio

5. You try…continued!

7. You Try…continued! Which player has the greatest free-throw ratio?
How is this shown on the grid?
Write the percents in order from least to greatest.

8. Connecting Fractions and Percents
You can use a percent bar model to model a ratio expressed as a fraction and find an equivalent percent
Complete the worksheet provided
Now let’s try a few problems
Ex 1: Use a percent bar model to find an equivalent percent for and 1 3
1B starts here 11/04/16

9. Benchmark and Proportional Reasoning
You can use certain benchmark percents to write other percents and to estimate fractions
Some of our benchmark percents are: 10%, 25%, %, 50%, %, 75%, and 100%
What would be an equivalent percent for ?
76% of the students at a middle school bring their own lunch. About what fraction of the students bring their own lunch?
